这Fraunhofer Institute for Laser Technology（ILT）和德国机床制造商特朗普have signed a cooperation agreement to accelerate the transfer of technology to industry within the field of laser metal deposition.
合作伙伴将在激光系统技术和针对特定的专业知识方面结合其各自的专业知识，以进行研究和开发，以提高其客户激光材料沉积的生产率，速度，材料和过程。
“我们的核心业务正在开发适应应用程序的流程和系统技术组件，” Fraunhofer ILT激光材料沉积能力领域负责人Thomas Schopphoven博士说。“这样做的基础是我们在激光材料沉积方面的30年经验 - 在我们为各种行业开发的应用中。
“当我们将技术转移到工业应用中时，我们的客户越来越关注系统工程实施的问题，尤其是在组件的可用性，稳定性和适用性方面。”
推进激光材料沉积
Fraunhofer Ilt最初开发了其专利Extreme High-Speed Laser Material Deposition（EHLA）3D打印技术于2017年。EHLA是该研究所对高量的定向能量沉积（DED）的看法，最初是作为模块化工具头提供的，可以集成到巨质和机器人臂中。该研究所将其EHLA技术描述为传统覆层过程的更有效且对环境友好的替代方案。
自该技术发布以来，Fraunhofer Ilt与多个合作伙伴合作开发了该过程的下一代版本，该版本更适合3D打印应用程序。2020年，抓地力制造商Bilsing Automation将EHLA集成到其工作流程中生产许多专有产品，，，，including flexible grippers, handling devices, and forming tools.
不久之后，Fraunhofer Ilt与Max-Planck-Institute for Iron Research（mpie）使用ehla产生一个3D printed composite materialwith comparable characteristics to that of Damascus steel, and later announced its EHLA technology had been adopted by manufacturing service bureauToolcraft到修理和修改旋转对称组件在涂上腐蚀和磨损保护之前。
In October last year, Fraunhofer ILT began conducting a新的研究项目using the latest version of its EHLA technology, EHLA 3D, in partnership with Germany-based engineering firm蓬孔. Currently, EHLA 3D can process parts weighing up to 25kg, at speeds of around 200 meters per minute, with a very high precision of 100 microns.
A new cooperation agreement
Fraunhofer Ilt’s latest endeavor to further advance its EHLA technology will see the institute leverage TRUMPF’s decades of experience in manufacturing laser systems and components for laser material deposition and material processing.
特朗普is one of the world’s largest machine tool and laser producers for industrial manufacturers, and has built up a strong metal printing portfolio. Fraunhofer ILT will lean on the manufacturer’s know-how in manufacturing robust, reliable, and productive machines for laser material processing within industrial series production to accelerate the development of EHLA and its applications.
Trumpf的3D打印投资组合由自己的laser metal fusion(LMF) powered systems, the TruPrint1000，，，，2000，，，，3000，，，，and5000，，，，alongside its laser metal deposition-driven TruLaser Cell3000，，，，7040，，，，andDepositionLineoffering. From the beginning of this year, the firm will continue to provide Fraunhofer ILT with state-of-the-art laser systems with various optical systems and powder feed nozzles, in order to develop the processes and applications of its machines.
Schopphoven补充说：“这样，我们直接研究了与工业相关系统的过程。”“这使我们能够特别有效地将研究转移到客户应用程序中。”
这partners claim that “numerous promising applications” are in sight, such as more economical coating of passenger car brake discs, and greater protection from wear and corrosion of hydraulic cylinders.
According to Marco Göbel, TRUMPF’s Industry Manager in Ditzingen, the closer cooperation with Fraunhofer ILT is a win-win for customers of both partners. Going forwards, the partners are planning to expand their cooperation further still in other areas of laser materials processing.
“Thanks to the close cooperation with Fraunhofer ILT, we can offer solutions for the entire production chain from a single source,” he said. “By combining our system technology – optimized for industrial use – with processes adapted or specially developed for this purpose, we help customers all over the world benefit from these innovations.”
